This is an activity about the rotation of the Moon. Learners use a penny and a quarter to model that the Moon does indeed spin on its axis as it orbits the Earth. They find that the Moon keeps the same face toward the Earth, but receives...(View More) illumination from the Sun on all sides in turn. This activity is part of Explore! Marvel Moon.(View Less)

Learners model how Earth's tilt creates the seasons. They use their bodies to review the Earth's daily motions before investigating the reason for Earth's seasons in this kinesthetic exploration. The motion of the Earth about its axis (rotation) and...(View More) in orbit around the Sun (revolution) is related to the appearance of the sky over the course of the day and year. Next they model that if the Earth's tilt was not stabilized by Moon, Earth's axis would slowly wobble between straight up (0° tilt) to nearly on its side (80° tilt). The resulting seasonal extremes would be unfavorable for life. Note that this activity is appropriate for children who are able to explore the geometry of Sun-Earth-Moon relationships in three dimensions. This activity is part of Explore! Marvel Moon.(View Less)

Learners use a Styrofoam ball, sunlight, and the motions of their bodies to model the Moon's phases outdoors. An extension is to have children predict future Moon phases. This activity is part of Explore! Marvel Moon.

Learners select from a variety of fruits to construct a scale model of the Moon, Earth, and Sun. After determining the correct sizes and distances for their models, they remove the Moon. They consider what it would be like if the nearby Moon were no...(View More) longer reflecting the Sun’s light in the nighttime or daytime sky. This activity is part of Explore!

In this inquiry investigation, students study the motion and positions of the Earth and how they affect the path of sunlight we get in different places. They discover that the Earth must be curved to account for the different lengths of shadows at...(View More) different latitudes and that the Sun is very far away. Supplies required include globes, blue-tak, toothpick, flashlights, and golf tees. This is the seventh of 10 inquiry investigations in Threads of Inquiry: Observing the World Around Us. Each lesson includes teacher background information, a narrative that models and describes the inquiry process applied in the lesson, and a hands-on inquiry investigation. Literacy extensions and a non-linguistic pre- and post-assessment are also included.(View Less)

In this inquiry investigation, students conclude that the motion of the Earth is linked to the changes we observe such as the length of the day. Students learn about the reason behind the Earth's time zones. An optional water clock and sand clock...(View More) making activity supports this investigation.

In this inquiry investigation, students discover how a given amount of light changes in intensity when the area it shines on changes, and that change in light and heat occurs when the Earth is tilted towards or away from the Sun. Supplies required...(View More) for the lessons include clipboards, thermometers, graph paper, and flashlights.
